When people recover from strokes or concussions, the same sort of
rewiring takes place in many regions of the cortex. Even language, one
of the most basic human functions, can be relearned after it has been
demolished by brain damage, through the synaptic rewiring of cortical
regions that previously took care of other business. For example,
following a stroke to language areas in the left hemisphere, the right
hemisphere will often increase its participation in language functions,
greatly facilitating language recovery. Thus, neuroplastic change can and
does occur in real life, with a speed and vigour we rarely imagine.
Back to addiction. People learn addiction through neuroplasticity,
which is how they learn everything. They maintain their addiction
because they lose some of that plasticity. As if their fingers had become
attached together, they can no longer separate their desire for well-being
from their desire for drugs, booze, or whatever they rely on. Then, when
they recover, whether in AA, NA, SMART Recovery, or standing naked
